Summary of the performance of TAPB-TFPA and TAPB-OMePDA COF aerogels for the absorption of organic solvents. (a,b) Digital photographs of absorption of (a) dyed chloroform and (b) dyed silicon oil from water. (c,d) Organic solvent absorption capacities of (c) TAPB-OMePDA COF aerogel and (d) TAPB-TFPA COF aerogel. (EtOH: ethanol; DMAc: dimethylacetamide; MeOH: methanol; DCB: dichlorobenzene; THF: tetrahydrofuran; DMSO: dimethyl sulfoxide). (e) Performance of the TAPB-TFPA COF aerogel over multiple cycles of absorption of chloroform and (f) PXRD spectra of the recycled TAPB-TFPA COF after multiple cycles of absorption, washing, and drying.
